Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468856, here are decompositions:

7 + 31468849 = 31468856
79 + 31468777 = 31468856
157 + 31468699 = 31468856
283 + 31468573 = 31468856
313 + 31468543 = 31468856
409 + 31468447 = 31468856
457 + 31468399 = 31468856
487 + 31468369 = 31468856

Showing the first eight; more decompositions exist.
